To all whom it may concern:

Be it known that I, GEORGE SHALL, of the village of Grosse Isle, 1n the Province of Manitoba, Canada, have 1nvented certain new and useful Improve.-

rnents in Building Construction, of which.

the following is the specification.

My invention relates to an mprovementin building construction and the object of the invention is to primarily provide a new form of block for building purposes'especially designed for a hollow wall construction and further to provide a means for reinforcing the wall so constructed and for attaching the wall to the usual steel framework of the building.

With the above object in view the invention consists essentially in the arrangement and construction of parts hereinafter more articularly described and later pointed out no the appended claims.

Figure 1 is a side view of one of my blocks. Fig. 2 is a plan view of a section of a wall formed in accordance with my invention, Fig. 3 is a longitudinal sectional view through the wall, the section being taken in the plane denoted by the line XX' Fig. 2. Fig. 4 is a vertical sectional view through the walls, the section belng taken in the plane denoted by the line Y-Y Fig. 3. Fig. 5 is an end View of'one of the blocks; Fig. 6 is a plan view of a further portion of the wall showing a modified form of reinforcing bar. Figs. 7 and 8 are views of the assembled wall with my device in use.

In the drawings like characters of refer-v V-shaped groove 41. and at the opposite end with an extending V-shaped tongue 5. The

. corners of the block are notched away on the MILLERMAB-z Two companion parallel structures or walls 16and 17 are erected side by side, each wall being formed from a number of my blocks built in with mortar in much the same manner as brick is now laid. ,The companion walls are built at-the same time and'as soon as the first layer is laid, it being understood that the tongues and grooves at the ends of adjoining blocks are fitted one into the other. Binding strips 18' of a diamond shaped cross section are laid in cement in the grooves 2 and a second layer of the blocks is placed on each of the companion walls, it being desirable to stagger or alternate the joints formed at the ends of the blocks in each layer. This operation is continued to whatever height it is desired to build the hollow wall and as the building operation proceeds it is necessary for strengthening purposes to tie the companion walls together. This is accomplished by laying in or inserting at proper intervals reinforcing bars 19. .lh'ese bars are more or less in the form of an I-beam in cross sec tion which permits the heads 19 and 19 I 19 to be laid in the wall as the bodies of the bars pass in the com leted structure through the diamond shape I openings, the ends 19 and 19 being received in the grooves 2 and '3 as already described. It is of course understood that bars 18 will be omitted from the portions of the grooves 2 and 3 which receive the ends 19' and 19 of the bars 19.

By exercising a little care, a builder would have no difficulty in placin these bars. 19 in the wall as the notches an out out corners will so to speak register with little difiiculty if the various layers are laid carefully and properly. The outer faces of the companion walls will present a smooth surface as the corners of the block are not cut away, neither do notches appear in them on this side. I might mention, that if at any time, through improper laying it is found impossible to fit in a reinforcing bar where desired, this can be readily accomplished by the-mason knocking ofi the required corners his trowel. j

The bars as above described are mounted for the most part in the wall. At points Where it is desired to connect the wall with an adjoining steel structure forming in reality the frame-Work of a building I have supplied a modified form of bar much the same as the one just described with the ad-' I dition of an extending finger-or arm 20 .(see. Fig. 6), the finger being also diamond shaped in said grooves, the end of said bars adapte in crosssection.

In Fig. 6,-21 represents a portion .of a

vertically disposed I-beamformin'g part of the steelstructure of a building. In order to connect my wall with the steel structure I insert in the wall and adjoining the I-beam a number of reinforcing bars of the second form instead of those 19. They are placed so that the arms or fingers 20 appear on opposite sides of the I-beam passing around the flange'and butting in against the web.

Preferably the bars 20 are staggered, that is not more than one bar being placed in the same groove. a I

This construction anchors the wall to the beam and conset uently to the erected steel structure. Where these latter bars areplaced .in the wall the mason will have to notch away sufficient of the blocks to allow the arms to protrude through the inner face of thewall; In other words, the notch located v in the center of thethe block will have to be continued completely across the block While the adjoining corners of the blocks in the next layer; adjoining the notch, will have to be knocked entirely oii, thereby forming a 1. The combination with compani diamond shaped opening on the outer side of the block similar to that reviously referred to on the inside of the Block.

What I claim as my invention is:

'on walls com osed of spaced apart blocks havin notc es in the inner side edges thereof an being provided with grooves intheir top and bottom edges, of a vertically disposed beam, bars connecting and reinforcing the companion walls, said bars having heads fitting to enter said notches,-and certain of said bars having fingers passing beyond the inner face of the wall and receiving the beam afore- 1 said.

2. The combination with companion walls composed of spaced apart blocks having tioned bars being adapted to enter the notches in the inner, side edges of said blocks.
